UNTTEU FREDERICK J. W. BARROW, OF CHICAGO, ILLINOIS.

DOOR-HINGE.

1 o (.IZZ whom it may concern.

Be it known that FREDERICK J. W. BAR- now, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Door-Hinges, of which the following is a specification.

This invention relates to doors and the hinge mountingthereof, and its object is to provide a structure that will leave no space between the hinge edge of the door and the door casing, and hence eliminate all danger of persons getting their hands caught and injured.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

1n the drawing,

Figure 1 is an elevation of the door; Fig. 2 is an enlarged section on the line 22 of F 1; Fig. 8 is a view similar to Fig. 2 showing the door partly open; Fig. 4 is an enlarged section on the line 44 of Fig. 1;

ig. 5 is a vertical section on theline 5-5 of Fig. 1; Fig. 6 is a view similar to Fig. 4 showing a modification, and Figs. 7 and 8 are sectional details showing further modifioations.

Referring specifically to the drawing, 10 denotes a door and 11 one of the sides of the frame to which the door is hinged. Fig. 1 shows the door fitted with two hinges, and as they are alike, a description of one suffices for both.

The hinge member which is secured to the door 10 is composed of a base or attaching plate 12 and cylindrical knuckles 13 integral therewith, and the hinge member which is secured to the casing 11 is composed of a base plate 1/1 and integral cylindrical knuckles 15. Each hinge member has two knuckles which are spaced so that when the members are assembled the knuckles are all in axial alineinent. It will be understood of course that the hinge members may be pro vided with any number of knuckles. The pintle of the hinge is a hollow cylinder 16 which seats in the knuckles 13 and 15, and provides the pivotal connection between the two hinge members as usual.

The base plate 12 of the hinge member which is to be attached to the door is ar- Specification of Letters Patent.

with respect to the i beyond the plane of the face of the door, and

locates the other half between the edge of the door and the edge of the door casing 11 to which is attached the hinge member composed of the parts 14: and 15, and this lastmentioned hinge member occupies a corr sponding relation with respect to the door casing.

In order to close up on one side of the doorthose portions of the space not occupied by the hinges, there is attached to the casing 11 a molding strip 18, and on the opposite side the space is closed up by a molding strip 19 carried by the door 10, the latter strip being secured to project from the hinge edge of the door. The strip 18 is three quarters round in cross section, and it IS fitted over the corner of the casing as shown in Fig. 4. Where the hinge member of the casing is attached, the casing 18 recessed to a depth to locate the knuckles 15 in alinement with the knuckles 13, the width of the space between the door edge and the recessed casing edge at the hinges corresponding to the external diameter of the knuckles 13 and 14-. The strip 18 is therefore in axial alinement with the hinge knuckles and it completely closes up on one side of the door the gap between the hinge edge thereof and the opposite edge of the door casing. The strip 19 for closing up this gap on the other side of the door, is secured to the face of the door and it projects beyond the hinge edge thereof close u to the casing edge to tangentially fit the molding 18 at this side. The strip 19 is also continued across the hinges to cover the gap between the base plates 12 and the knuckles 13. The strip 18 however is not continuous but is made in three sections, one section seating between the hinges, and the other sections above and below the hinges ends of the knuckles permit ready application of the fasteners 17,

as shown in Fig. 1, and adjoining the hinges, the ends of the sections are reduced to form tenons 20 which seat in the-hollow pintles 16, and thereby assist to hold in hinge members in assembled relation.

Fig. 6 shows a molding strip 21 for the same purpose as the strip 18, but shaped somewhat differently. This strip is to be used where the hinge recesses of the casing are continuous from the top to the bottom of the casing, said strip 21 being shaped to fill up the recess beyond the site of the hinges.

Figs. 7 and 8 show molding strips-22 and 23, respectively corresponding to the moldin g strip 19 but somewhat different in shape, they being substantially triangular 'to fitinto the space between the plate '12 and the knuckles 13.

It will be evident from the foregoing that the crack between the door and itscasing is completely covered at all times and irrespective of the position of the'door, and hence all danger of persons getting their hands caught and injured ing and the door edge is eliminated.

.As shown in Fig. 1, the base plates 12 and 14c of the hinge members project from the a sufficient distance to the holes forthe latter being in the projecting ends of the base plates.

I claim: 1. The combination with a door and the casing to which it is hinged, of a hinge consisting of similar members each of which is composed of' an attaching plate and knuckles, the knuckles of the two members registering, and a pintle passing through. the registering knuckles, strips carried by the casing for closing up on one side of the door the gap between the casing edge and the opposite edge of the door beyond thehinges, said st-rips being in alinement wit-h the hinge between the cas knuckies and coinciding in cross-section to the cross-sectional contour thereof, and a strip for closing up said gap on the other side of the door, said last-mentioned strip being carried by the door and also extending across the hinges to cover the gap between the door and the knuckles of the.

hinge membercarriedby the door.

2. The combination with a door and the easing to which it is hinged, of a hinge consist- .ing ofv similar Inemberseach of which'is composed of an attaching plate and knuckles, the knuckles of the two. members registering, and a pintle passing through the registering knuckles, said pintle being hollow, strips carried by the :casing for closing up on one side of the door the gap betweenthe casing edge and the opposite edge of the door beyond the hinges, said strips being in alinement with the hinge knuckles and coinciding in cross-section to the cross-sectional contour thereof, the endsof the strips having tenons which seat in the aforesaid pintles, and a strip for closing up said gap on the other'side of the door, saidlast mentioned strip being carried by the door and also-extending across the hinges to cover the gap between the door and the knuckles of the hinge member carried by the door.

3. A hinge comprising a pair of attaching plates having matching knuckles adapt ed to receive a pintle, said knuckles being offset laterally with respect' to the plates,

each of said plates extending tangentially with respect to its knuckles and having a length from the front to the rear which is less than the diameter of the knuckles, to locate the knuckles partly opposite the face of the plate and partly projecting beyond the plate. 7 e

testimony whereof I affix my signature.
